I always use '-j -q', unless I test specific packages or need to debug
build error.

I think this is an issue with your bash version. The code for this message
is this:
[...]
echo "${PTXDIST_LOG_PROMPT}error: $1" >&${PTXDIST_FD_STDERR}
[...]

I think older bash versions have a problem with this under some
circumstances. I don't remember all the details, but it may be triggered by
the call chain 'bash -> make -> bash'. The fd is  opened in the first bash
and used in the second.

Can you send the relevant parts from the logfile? I know there is a
dependency problem in openssl. I cause very rare build errors. I've yet to
figure out the exact cause. It's not '-j' specific but that seems to
trigger it more often.

I'm not aware of any problems with busybox. A log with some more details
would be helpful.
